Objective: To evaluate the benefit of anatomical muscle dissection repair for velopharyngeal insufficiency (VPI) in patients with submucous cleft palate (SMCP) with 22q11.2 deletion syndrome. Design: Retrospective blinded randomised analysis of a surgeon's management over 10 years. Setting: The study was performed at a specialised Paediatric hospital in the United Kingdom. Patients: Children with SMCP and 22q11.2 deletion syndrome. Interventions: All participants underwent radical muscle dissection veloplasty. Outcomes measured: Pre- and post- operative measurements included severity of anatomical defect, speech samples and lateral images which were digitised, randomised then externally and blindly analysed using validated techniques. Stata software was used to perform statistical analysis. Results: 57 children with 22q11.2 deletion syndrome were included in this analysis. Intra-operatively, the majority of cases were identified as SMCP Grade I anomalies. Post-operatively, a statistically significant improvement in hypernasality, resting palate length, palate length at maximum closure, palate excursion and gap size at maximum closure was observed. Secondary surgery was performed for 59% of patients by ten years. Conclusion: Muscle dissection repair improves hypernasality, palate closure function and the closure gap in patients with 22q11.2 deletion syndrome. Although over 50% of patients may require further surgery, muscle dissection repair should be a first step due to its utility at a younger age, when invasive investigations are impossible, its lower morbidity, speech and language benefits or altering the plans for less obstructive secondary surgery when it lead to reduced velo-pharyngeal gap and improved palate mobility even when adequate velo-pharyngeal closure was not achieved.

Objective : To delineate the indications, referral sources and outcomes of radical muscle dissection palate repair in the first 4 years of life for patients with submucous cleft palate (SMCP). Design : This study presents a retrospective analysis of a single surgeon's management. Setting : All children were treated at Great Ormond Street Hospital, United Kingdom. Patients : Twenty-three children with nonsyndromic SMCP were included in this study. Interventions : All participants underwent radical muscle dissection repair before their fourth birthday. Outcome Measured : Parameters analyzed included: referral sources, indications for referral, extent of anatomical abnormality, and postoperative outcomes. Results : Paediatricians provided the largest proportion of referrals to the cleft lip and palate clinic (39%) due to the presence of cleft lip/palate on prenatal scans or during neonatal examination. Over half (n = 12, 52%) of patients had severe anatomical anomalies being in grade IV (score 8-9), with the classical triad present to some extent in all but 2 of the patients. The main indication for surgery was nasal regurgitation of food and liquid (n = 9, 35%) followed by hypernasality (n = 6, 21%), difficulty feeding (n = 3, 8%), and severe anatomical defect (n = 2; 4%). Postoperatively, the presenting complaint improved in the majority of cases. Conclusion : Nonsyndromic SMCP is often missed, though may present with nasal regurgitation, feeding problems, and/or hypernasality, though may be missed in nonsyndromic children. Early radical muscle dissection repair in the first 4 years of life is safe and effective, facilitating normal speech development. [ABSTRACT FROM AUTHOR]

Background: Cosmeceutical products are an important therapeutic option for facial rejuvenation. Of these, topical application of growth factors has been shown to increase dermal collagen synthesis, improve skin texture, and reduce fine lines and wrinkles. Limited data exist for the use of growth factors in combination with microneedling. Objective: This prospective, single‐center, uncontrolled study evaluated the efficacy of topical growth factor treatment in conjunction with transdermal delivery of growth factors via home‐based microneedling for facial skin rejuvenation. Patients/Methods: Eleven healthy female individuals aged 33–61 years, with mild‐moderate facial wrinkling were included in the study. Over 3 months, participants received twice‐daily application of a topical recombinant human growth factor preparation (SkinGenuity® Regenerative and Reparative Serums) along with twice‐weekly transdermal delivery of growth factors using a home‐based microneedling (0.2 mm) device. Objective skin analysis (VISIA®) and a subjective patient‐reported outcome (FACE‐Q®) assessment measuring satisfaction with appearance were performed at baseline and after 3 months. Results: Objective skin analysis showed a significant improvement in skin texture (17.6%, p < 0.001), wrinkles (17.3%, p < 0.001), red areas (12.4%, p =0.004), and brown spots (6.0%, p =0.03) at 3 months follow‐up. FACE‐Q scales showed a significant improvement from baseline, including satisfaction with skin, facial appearance, nasolabial folds, cheeks, and lower face/jawline (all p ≤ 0.02). Numerical improvement in adverse effects related to skin was also observed (p = 0.07). No serious adverse effects were reported. Conclusions: Three months of twice‐daily topical growth factor treatment in conjunction with transdermal delivery of growth factors via microneedling improved skin analysis parameters and participant‐reported outcome measures, indicative of facial skin rejuvenation.

Background  Augmented reality (AR) uses a set of technologies that overlays digital information into the real world, giving the user access to both digital and real-world environments in congruity. AR may be specifically fruitful in reconstructive microsurgery due to the dynamic nature of surgeries performed and the small structures encountered in these operations. The aim of this study was to conduct a high-quality preferred reporting items for systematic reviews and meta-analyses (PRISMA) and assessment of multiple systematic reviews 2 (AMSTAR 2) compliant systematic review evaluating the use of AR in reconstructive microsurgery. Methods  A systematic literature search of Medline, EMBASE, and Web of Science databases was performed using appropriate search terms to identify all applications of AR in reconstructive microsurgery from inception to December 2018. Articles that did not meet the objectives of the study were excluded. A qualitative synthesis was performed of those articles that met the inclusion criteria. Results  A total of 686 articles were identified from title and abstract review. Five studies met the inclusion criteria. Three of the studies used head-mounted displays, one study used a display monitor, and one study demonstrated AR using spatial navigation technology. The augmented reality microsurgery score was developed and applied to each of the AR technologies and scores ranged from 8 to 12. Conclusion  Although higher quality studies reviewing the use of AR in reconstructive microsurgery is needed, the feasibility of AR in reconstructive microsurgery has been demonstrated across different subspecialties of plastic surgery. AR applications, that are reproducible, user-friendly, and have clear benefit to the surgeon and patient, have the greatest potential utility. Further research is required to validate its use and overcome the barriers to its implementation. [ABSTRACT FROM AUTHOR]

Background: Hyaluronic acid (HA) dermal filler injection is believed to be a safe procedure. However, with the increase in the number of performed procedures and indications, the number of product-related complications, especially delayed inflammatory reactions, has also increased. Delayed-type hypersensitivity (DTH) reaction is one of these delayed inflammatory reactions, which is preventable by performing a pretreatment skin test.Objectives: The authors sought to find the incidence of delayed inflammatory reactions and DTH reaction after HA injection and to determine whether a pretreatment skin test is worthwhile to be performed.Methods: The authors conducted a systematic literature review of all the relevant prospective studies, retrospective studies, and case reports on delayed inflammatory reactions and DTH reaction after HA filler injection.Results: The incidence of delayed inflammatory reactions calculated from the prospective studies was 1.1% per year, and that of possible DTH reaction was 0.06% per year. Most retrospective studies estimated a percentage of delayed inflammatory reactions of less than 1% in 1 to 5.5 years. The incidence of DTH reaction would be lower than that. Among all the DTH cases reported, only about 5% of them were proven to be genuine DTH reactions.Conclusions: The incidence of both delayed inflammatory reactions and DTH reaction is low. There is evidence that genuine DTH reactions caused by HA fillers approved by the Food and Drug Administration do exist. This adverse event can be prevented by performing a pretreatment skin test. However, the incidence of DTH reaction is so low that the pretreatment skin test is not mandatory if Food and Drug Administration-approved HA fillers are used.Level Of Evidence:4: [ABSTRACT FROM AUTHOR]

Background: Migraine is a severe, disabling condition, ranked by World Health Organization as the sixth highest cause of disability worldwide. It greatly affects patients' quality of life, functionality, and physical and mental health. The financial burden of migraine on the UK economy is conservatively estimated at £3.42 billion per year.Objectives: The authors sought to perform an evidence-based literature review of the safety and efficacy of botulinum toxin type A (onaBoNTA) in the prophylactic treatment of adult patients suffering with chronic migraine (CM) compared to placebo. After the best evidence is identified, it will be utilized to formulate a protocol for doctors managing CM in their aesthetic clinic.Methods: A comprehensive search of the current literature on the topic was performed by H.M. using Pubmed MEDLINE electronic database on March 1, 2018. All articles up to and inclusive of this date were included. Articles were limited to human studies and those in the English language. In vitro and animal studies were excluded.Results: A total of 260 articles were identified. Of these, the excellent-quality, high-strength (level 1A) trials were short-listed to answer the research question.Conclusions: There is high-quality, level 1A evidence to support onaBoNTA treatment in adults with CM is well tolerated and considered safe. However, it is associated with increased risk of adverse events and still some uncertainty exists associated with the degree onaBoNTA improves outcome measures compared to placebo. These data have been used to formulate The London Aesthetic Migraine Protocol (LAMP) to provide safe, evidence-based guidance for appropriately trained and experienced aesthetic practitioners to manage CM in their aesthetic clinics.Level Of Evidence:1: [ABSTRACT FROM AUTHOR]

Objective: Microsurgical education is an integral aspect of plastic surgery training. Like most traditional surgical education models, microsurgical skills are taught on an apprenticeshipmodel. This study aims at evaluatingmicrosurgery skill acquisitionwithin an integrated plastic surgery residency using electromagnetic hand-motion analysis and a global rating scale. Methods: This is a cross-sectional study of an integrated plastic surgery residency program. Participants performed microsurgical arterial anastomoses on cryopreserved rat aortas. Hand-motion analysis was recorded using a trakSTAR hand-motion tracker. Total time to complete the task, number of hand movements, and path length (mm) were recorded. Participant videos were graded using a subjective global rating scale (scored 0-100). Results: The data demonstrated construct validity, as hand-motion analysis outcome measures statistically varied according to the level of skill. Mean global rating scale scores increased with level of experience but lacked statistical significance. Conclusions: These data suggest that the objective assessment of hand motion is a valid tool for the evaluation ofmicrosurgical skill. It is more accurate and reflective of the level of skill than a global rating scale. Identifying the predictive validity of hand-motion analysis will be a useful tool to establish clinical safe training and practice thresholds, and the application of both assessment tools simultaneously can yield better evaluation.

Background The aim of this article is to evaluate the difference in skills acquisition of two end-to-end microvascular anastomosis techniques--the triangulation and biangulation--in early microsurgery training. Method In this study, 32 candidates ranging from medical students to higher surgical trainees underwent a 5-day basic microsurgery course. On days 3 and 5 of the course, candidates performed two end-to-end anastomoses on cryopreserved rat aortas. One anastomosis was performed using the biangulation technique and the other using the triangulation technique. Candidates were randomized to the order of technique performed. Structural patency, errors performed, and suture distribution were evaluated randomly by a blinded reviewer using the anastomosis lapse index score and Image J (U.S. National Institutes of Health, Bethesda, MD) Software. Results A total of 128 anastomoses were evaluated during the study period. A total of six anastomoses performed with the biangulation technique, and four anastomoses with the triangulation technique, were physically occluded on day 3 of the course. On day 5, two biangulation technique anastomoses and one triangulation technique produced a nonpatent outcome. There was a statistically significant difference of patency rate between the 2 days of evaluation confirming evidence of skill acquisition but no statistically significant difference between the two techniques in relation to anastomotic patency, errors performed, or suture placement quality. Conclusion The biangulation and triangulation techniques of microvascular anastomosis produce similar outcomes in relation to vessel structural patency and quality of anastomosis when taught in early stages of microsurgery training. Our results suggest that both techniques are equally suitable in training novices, basic microsurgical skills. [ABSTRACT FROM AUTHOR]
